How does this work?

HeiQ Viroblock NPJ03 is a Swiss textile technology that is added to the fabric during the final stage of the textile manufacturing process. It uses the combination of HeiQ’s advanced silver technology and a vesicle technology as a booster. Silver admits silver-ions to inhibit bacteria on the fabric surface. The vesicle technology depletes the viral membrane thus silver can work more efficiently and rapidly to attack the core of the virus. The treated products last up to 30 washes at 60°C.
